An example of a punnet square is if you have the heterozygous Bb genotype. The punnet square would have a big B and a little B at the top and on the side. The first square would be BB, the second one would be Bb, the third would be Bb, and the fourth would be bb. the possibility that the child has the bb genotype is 1/4.
To fill in a Punnett square, list the possible alleles from each parent along the top and side of the square. Then, combine the alleles in each box to determine the possible genotypes of the offspring. Finally, calculate the frequencies of each genotype based on the Punnett square outcomes.
A punnet square is used to work of genotypic and phenotypic ratios for different crosses of animals. Therefore in a punnet square you will find the genotypes of the offspring that resulted from the cross (mating).
Take the phenotypes of the two parents and have them above and next to a box:
(say that the mother is AA and the father is Aa)
....A A
A AA AA
a Aa Aa
Genotypic ratio: 2 homozygous dominant: 2 heterozygous: 0 homozygous recessive
Treat it like a multiplication table. Take the allele from the top and the allele from the side to get two alleles in each box. (If the dominant allele is present, have it be first)

How do you put RrYY in a punnet square?
To fill out a Punnett square for a genotype like RrYY, you would list the possible alleles for each parent horizontally (Rr for one parent, and YY for the other) and vertically. Then, combine the alleles to fill in the squares (RY, Ry, rY, ry) to show the possible genotypes of offspring resulting from this cross.

What does a capital letter such as T represent in a pundit Square?
A capital letter in a Punnet Square represents a dominate allele.
What is a chart that shows all possible allele combination resulting from a genetic cross?
A Punnett square is a diagram used to predict the possible genotypes of offspring in a genetic cross. It displays all possible combinations of alleles that parents can pass on to their offspring.
How do you work a punnet square?
A punnet square is a box of 4 sections
What is a non-example for a punnet square?
A banana is a good example of a punnet square since it has absolutely nothing to do with a punnet square.
How do you work punnet squares?
A punnet square is a box of 4 sections
What is the punnet square for?
the punnet square is used for combining genes of two people or animals to predict the outcome of an offspring

What use is the punnet square?
the punnet square is used for combining genes of two people or animals to predict the outcome of an offspring
Where was the punnet square made?

Does a punnet square show the genotype?
no
What does a punnet square capital letter stand for?
A capital letter in a punnet square stands for a domminant trait, or one that will most likely appear. --Stew Pidacel
What is punnet squares?
A punnet square is a diagram showing the gene combination that might result from a genetic cross and it can be bigger than 2x2A diagram that is used to predict an outcome of a particular cross or breeding experiment is called punnet square.
What is a tool for predicting traits of offspring?
Punnet Square
What is an antonym of punnet square?
A punnet square is a tool used in genetics to predict possible combinations of alleles. An antonym could be something like "random chance" or "unpredictable inheritance."
